In the pressing of clothes or cloth by means of ironing machines, in which the goods to be ironed are treated with steam, these goods become so damp owning to the steam treatment that it has been found necessary to adopt special measures whereby the goods to be ironed can be removed in a dry state from the machine. For this purpose, the press bodies have already been fitted with steam damping and suctioning plants, in order to effect the drying of the material by means of a suctional current. This suctional current passed through the material from the outside inwards, but this however was accompanied by the disadvantage that the drying current naturally turned over the fibres or the pile on the surface of the material and pressed it downwards, thus producing, and more particularly on dark fabrics, the shininess Which is so much to be dreaded when ironing. In order to eliminate this shininess and as is well known a number of time consuming manipulations had to be carried out which however for the most part adversely affected the smoothness and the shape of the material under treatment. Further, in the process 0 drying by means of suction, there was always the disadvantage that the current of air used for drying purposes had always to be drawn from the atmosphere in the work room, which as every one knows is very moist owing to the work having to be done on steam presses and is consequently very little adapted for drying purposes.

In accordance with the present invention, the drying of the material is efiected, after the ironing pressure has been released, by means of dry compressed air which coming from the press body flows through the ma- 40 terial from the inside outwards in such a way that the pile on the material is raised in the direction of the current of air during the drying process, so that the tiresome shininess is avoided. This process has, further, the

advantage that the current of air used for elminnating the steam and the moisture from the material can be previously dried as required or, if need be, can be heated, although this is not possible in the familiar suctioning processes. This is important in so far that non GARMENT PRESSES 307,762, and in Germany September so, 1927. I

the pressing process is very much improved in proportion to steam and drie shininess.

After the material has been steamed and pressed, the

valve 5 is opened by means of a hand or foot lever, whereupon compressed air enters into the steam pipe 3*.

This air first of all forces any steam that may have remained behind in the pipe 3* through the material,
